Pitching Matchup

Miami Marlins - Janson Junk

Junk is 6-8 with a 4.21 ERA and 1.30 WHIP through 98.1 innings. The right-hander has allowed 102 hits and 26 walks while recording 68 strikeouts. Junk has surrendered 12 home runs. His walk total has remained relatively low for his workload, but opponents have collected more than one hit per inning. Junk’s 68 strikeouts are also well below Alvarez’s total despite pitching nearly 14 more innings this season.

Washington Nationals - Andrew Alvarez

Alvarez is 2-6 with a 3.72 ERA and 1.35 WHIP across 84.2 innings. The left-hander has allowed 76 hits and 38 walks while striking out 80. Alvarez has surrendered only five home runs, seven fewer than Junk. His 3.72 ERA is also lower than Junk’s 4.21 mark. The 38 walks have increased his WHIP, but Alvarez has countered too many baserunners with more strikeouts and limited damage from home runs.
