tapping into power

Brent Rooker hit his 30th homer of the season on Thursday, a first-inning two-run shot that helped the A’s deal playoff-chasing Boston a hard loss at Fenway Park. Rooker, the former All-America from Mississippi State, now has 99 homers in three years with the A’s. It’s weird to think that in his first three MLB campaigns (2020-22) he hit a grand total of 10 homers while barely playing with three other clubs. The A’s got the former 35th overall pick as a waiver claim from Kansas City in November 2022. Of note: Fellow MSU product J.T. Ginn pitched six effective innings Thursday to get the win; the second-year right-hander is 4-6 with a 4.57 ERA in 22 appearances this year. With the defeat, Boston fell to third in the American League wild card standings. … Former Mississippi College star Blaine Crim belted two 400-foot homers for Colorado and now has three in seven games with the Rockies. Crim, getting his first real opportunity in the big leagues in his sixth pro season, has 124 minor league homers on his ledger. … Down in the minors, Kemp Alderman, third-year pro from Ole Miss, slugged his seventh homer in 17 games since being promoted to Triple-A Jacksonville in the Miami chain. Alderman hit 15 bombs in Double-A this season. P.S. Biloxi was eliminated by Montgomery in the Southern League division playoffs. Ex-Magnolia Heights star Cooper Pratt, Milwaukee’s No. 3 prospect, hit .237 with eight homers, 62 RBIs, 71 runs and 31 steals in his first Double-A season.
