T-Sox Sweep State Playoffs

This past weekend was the Northern California AABC Connie Mack and Mickey Mantle State Tournaments. The Thunder Sox had 3 teams competing in the tournaments this weekend. In the 18U Connie Mack tournament our 18U Blue team was competing and in the 16U Mickey Mantle tournament we had our 16U Blue and White team. In the Connie Mack tournament our 18U club would start the tournament off with an extra inning loss to Alameda and would come all the way back through the loser’s bracket winning 5 straight games to claim the title. This epic run to the title was highlighted by some clutch performances on the mound and in the field. In game 3 Matt McDonald (Dublin HS) would fire 4 shutout innings out of the pen vs Bercovich to lead the team to a 4-0 win. The very next day Sonny Brandwood (Dublin HS) would fire a complete game 3 hit shutout over the tournament favorite CCB/NorCal. The best game of the weekend was easily the semifinals. Down 4-2 in the top of the 7th with 2 outs and no one on the T-Sox would string together a few hits to make it 4-3 with runners on the corners. Adam Hollar (Chabot College) would step to the plate and hit a game winning triple down the right field line. In the championship coach Sandoval turned to Cody King (Livermore HS) for the start on the mound. King was up for the challenge tossing 5 innings of 1 run ball and leading the team to a 2-1 victory over Alameda and claiming the title. Thunder Sox Connie Mack team will be competing in the Western Regional Tournament this coming week.


In the 16U Mickey Mantle tournament both of our teams showed extremely well. After the 3 pool play games the T-Sox White was 3-0 and claimed the 1 seed and the Blue squad was 2-1 and claimed the 3 seed. The white seed would fall 6-5 in the semifinals. The Blue team would go on a long run winning 3 games on Sunday to secure the title. The T-Sox Blue started the day off strong beating EJ Warriors 10-2 behind a complete game from Patrick Polcar (Cal HS). The next game vs Napa would prove to go just as well. RHP Drew McCarthy would breeze to a 70 pitch complete game, inducing 4 double plays and striking out 5 winning 9-2. In the championship the Thunder Sox would hand the ball to Dom Guintoli who fired 4 shutout innings before handing the ball to Frank Kudelka who would lock down the 2-0 win with 3 shutout innings out of the bull pen. 


JUNE 16, 2015 - Here is a quick roundup, highlighting a few former Thunder Sox players who have either made news or are primed to make news. If you would like to be highlighted in this space, contact us at and let us know what you're doing!


The Thundersox are happy to announce that Southeast Missouri State LHP Joey Lucchesi (2012) was named 2015 Ohio Valley Conference pitcher of the year. Joey was dominant for the RedHawks, going 7-2 with a 3.17 ERA and 93 strikeouts in 88 innings pitched. He allowed only 60 hits on the season. He had a pair of 13-strikeout games, as well as an 11-strikeout performance.


Chabot sophomore shortstop Ian Dawkins (2014) finished the season hitting .329/.447/.452 for the Gladiators, scoring 30 runs, knocking in 23 and stealing 12 bases. He walked 19 times, was hit by 13 pitches and only struck out 9 times in 182 plate appearances. Dawkins is commited to Louisiana Tech University for the 2016 season.


Jarvis Christian College junior RHP Dylan Martinelli (2012) led the team in saves as a junior with four, striking out 16 and walking 6 in 19 innings. Batters hit just .224 against Martinelli this season.


Cal State Monterey Bay outfielder Brian Hamm finished his senior season hitting .299 with 2 homers and 18 RBI in 99 at bats. He had an on-base percentage of .377 and stole six bases for the Otters.


Former Thunder Sox player and coach Mike Lonsdale finished his first season as an assistant coach at Cal State Monterey Bay. The Otters finished 32-20 overall, including 27-13 in the CCAA, earning another postseason bid.


Please take time to check out all of our former players making a name for themselves in college and pro ball.

April 8, 2015 - HIGH SCHOOL AGE PLAYERS: We with the Thunder Sox hope your high school seasons are going well!


The Thunder Sox are looking for more players at the high school level for the 2015 summer season and beyond. If you are interested in playing with the Thunder Sox, please contact Coach Lonsdale at (510) 909-6718 or


CURRENT THUNDER SOX PLAYERS: For high school age players who have been T-Sox in the past, contact Coach Lonsdale or Coach Gatehouse to let us know what level you are playing at and let us know how the season is going. If you have a teammate or opponent that we should take a look at, please let us know as well.

Make it a great day! Go T-Sox!


The Thunder Sox are excited to announce that LHP Thomas Triantos and RHP/INF Kyle Franco have accepted scholarships to top baseball schools in California.


Thomas has been with the Thunder Sox since he was 15 and was a standout this past season pitching for Livermore High School, earning second team all EBAL honors and finishing in the top of the league in strikeouts and ERA. This summer Thomas had a lot of buzz around him from colleges and they all accumulated at his start in Southern California at the Firecracker Classic. Around 20 D1 schools showed up to see Thomas pitch against the Desert Prospects, a top level club team from the Palm Springs area. Thomas was up for the challenge striking out 7 of the first 9 hitters he saw, registering his fastball as high as 89mph on the gun and throwing both of his offspeed pitches for strikes when needed. Although the team lost the game 1-0, Thomas was still flooded with multiple offers over the next few weeks. Riverside, Irvine, Long Beach, Hawaii, Nebraska, Davis, UOP & Fullerton all reached out showing interest in Thomas and offering generous scholarships but Thomas decided on Cal Poly-San Luis Obispo. Cal Poly was ranked number 1 in the country for a good part of the season the year before and was a host for the regional tournament. Thomas said he chose Cal Poly because they have his major, they are close to his family and he will have an opportunity to pitch as a freshman!

Kyle Franco, like Triantos, has been with the T-Sox since he was young. Kyle joined the program when he was 16 as one of our youngest players on our then 19U team. This summer Kyle was the ace pitcher at Foothill HS in Pleasanton finishing in the top of the league in strikeouts and wins. Kyle’s standout moment was in the playoffs against WAAC champs San Leandro HS. Kyle fired a CG no-hitter and collected 3 hits at the plate sending his team to the semi-finals of the NCS playoffs. Kyle committed to Chico State at the beginning of the summer after mulling over multiple offers from local D1, D2 and JR College schools. Chico State was high on Kyle because of his strong arm on the mound (92mph), his plus speed running the bases (6.7 60 yard dash) and his powerful bat. Kyle chose Chico State because they offered him a chance to be a position player and a pitcher, something he really wanted to do.

Other players heading to college are Zac Lander (Azusa Pacific Univ.), and Adam Hollar, Cameron Self, Jake Ruiz, Zac Maloney, Kevin Nava, Max Sanderson, Kevin Burt and Will Theofanopolous (Chabot College). 2014 grads: once you decide on where you are playing in college, we will post it here!


As the 2014 summer wraps up, the Thunder Sox feel this was our best summer yet. Players accepted scholarships, teams won championships and players developed. At the beginning of each summer, our goal is to put our players up against top level competition, get them in front of college coaches and win games/tournaments.

For the second year in a row our Connie Mack had a great showing at the Firecracker Classic in Southern California. This year there were 92 teams in the 18U bracket and our Connie Mack team made it to the Final Four. The team went 2-1 in pool play earning the two seed in their pool and advancing to the elimination round. After the first round of elimination games the T-Sox were the only two seed still alive. After blowing out the So Cal Phillies in their first elimination game the team took on the Old School Dirt Bags. The Dirt Bags had players flown in from Texas, Arizona & Colorado and were a very strong opponent. RHP Levi Noddin pitched the game of his life throwing a 77 pitch CG to send his team to the quarter-finals with a 3-1 victory. In the quarter-finals the T-Sox would face the Black Dogs from Chino, Ca. The T-Sox took an early 5-2 lead behind a HR from Levi Noddin and a 2B from Jake Ruiz, but the lead would not last. The T-Sox and Black Dogs went into the 12th inning tied at 5 with Nick Truex tossing 5 scoreless innings in relief. Jake Ruiz knocked in Kyle Franco with a two out triple in the top of the 12th to send the team to the final four. The T-sox would lose a heartbreaker to the eventual tournament champs Saddleback Devils 6-5.

Our Connie Mack club was not the only team to feel success this summer. Our 2015 team and our Frosh/Soph club both won the East Bay Summer League regular and post season championships! Our 2015 club, made up of 16 and 17 year old players, was competing in the 18U division of the EBSL. After finishing the regular season 8-3, they entered the playoff tournament as the favorite and did not disappoint. LHP Brian Martinez was solid on the mound, pitching 6 strong innings in the semifinals to send the team to the championship game. The 2015 club would face the SR Slammers, needing only 1 win to win the title and having to be beaten twice to surrender the crown. The Slammers won the first game of the championship round, but that was all they would get. RHP Hayden Berson took the mound in the championship game and was stellar, pitching 4 strong innings before handing it over to RHP Ryan Holmes, who would shut the door on the Slammers. Coach Dean was very proud of how his players came together as a team throughout the summer!

The Frosh/Soph club also entered the playoff tournament as the number 1 seed and would find themselves in the championship game. After knocking off Walnut Creek, San Ramon and Lafayette in the winners' bracket of the double elimination tournament, they would face the Lafayette Blues, who would have to beat them twice in the finals. RHP Clinton Law and the T-Sox would not let it get to a second game as they took take of business in Game 1. Law had been solid on the mound for the T-Sox all summer and saved his best game for last, firing an 85 pitch complete game to beat Lafayette 3-1. Nick Lievre and Dom Giuntoli were both standouts at the plate for the T-Sox all tournament.

JULY 4, 2014 - Happy Fourth of July all! The entire upper level program was down in Orange County this past week for the annual Firecracker tournament. It was a great chance for all three of our teams to compete against some of the best teams in the West. All teams enjoyed some success, but none more than the Connie Mack squad, who took a tough 6-5 loss in the semifinals on Thursday to finish 5-2 and in the final four of the 91-team pool. The coaching staff is extremely proud of the performances of our players in front of countless colleges and scouts. We hope to be announcing some commitment news soon!


Congrats to current Thunder Sox player Levi Noddin (Arroyo HS '15) on being selected to the 2014 Louisville Slugger All American 2nd team. Levi is a RHP & 1B and very dominant at both. This year for Arroyo, Levi was 10-2 with a 2.49 ERA, struck out 84 and only walked 18 in 73 innings pitched. At the plate he batted .442 and slugged .688 in 97 plate appearances. Levi has continued his dominace this summer as a two way player for the Thunder Sox on our Connie Mack club.
