Mejia extended his hitting streak to 24 games on Sunday, when he went 2-for-3 with a two-run home run for Class A Lake County. The 20-year-old backstop is hitting .430 with six home runs and 21 RBIs during the streak. On the season, Mejia, a switch-hitter, is pacing the Midwest League with a .347 average through 60 games, and he's also thrown out 43.5 percent (20 for 46) of potential basestealers.
Glasnow is coming off of back-to-back hitless starts for Indianapolis. The No. 8 overall prospect struck out six over six innings against Charlotte on June 17, and then came back to fire seven more hitless frames with eight strikeouts in his June 22 start versus Gwinnett. Glasnow struggled with his control in both outings, walking six and five batters, respectively. The 22-year-old right-hander's body of work this season is impressive, as he enters Monday leading the International League with a 1.61 ERA and 100 strikeouts.
Newcomb, No. 17 on the Top 100, made his longest start of the season last time out, firing seven innings of two-run ball against Birmingham. The 23-year-old lefty, whom Atlanta acquired last offseason from the Angels in the Andrelton Simmons trade, has pitched to a 3.96 ERA with 74 strikeouts against 37 walks in 72 2/3 innings (14 starts) for Mississippi.
Esch is looking to build on one of his better starts of the year for Jacksonville after he allowed one earned run and struck out seven over six innings on June 16 in a win over Biloxi.
