After playing for the World squad in the SiriusXM All-Star Futures Game, Mejia returned to Class A Advanced Lynchburg on Wednesday -- only to have the game suspended after his first at-bat. When it resumed Thursday, the 20-year-old backstop delivered a sixth-inning single to extend his hitting streak to 34 games, the longest in the Minor Leagues since 2011. Mejia has posted a .390 average with 53 hits during his streak, which began on May 27.
Faria has allowed one earned run on six hits in three starts since being promoted to Triple-A Durham. The 22-year-old righty has fanned 18 hitters over 15 innings during that stretch and enters the day third in the Minor Leagues with 111 strikeouts. Overall, Faria has pitched to a 3.66 ERA while holding opposing hitters to a .198 average in 98 1/3 innings (17 starts) between the Double- and Triple-A levels.
Ponce, 22, is coming off back-to-back scoreless starts for Class A Advanced Bradenton during which he combined to allow just five hits in 11 innings while punching out 17 without a walk. The 2015 second-rounder owns a 3.24 ERA and a 29-3 strikeout-to-walk ratio through 25 innings (seven starts), although he's still searching for his first win of the season.
Castillo's triple-digit heater and sharp slider have caused fits for Florida State League hitters, who are batting .224 with one home run against the right-hander. Additionally, the 23-year-old has recorded a 2.39 ERA and a 0.96 WHIP in his first full season as a starting pitcher, with 65 strikeouts and 12 walks in 83 innings.
