The Chicago White Sox (24-22) and the Seattle Mariners (22-26) open a three‑game series tonight at T‑Mobile Park. The White Sox are one of the biggest surprises in baseball. This past weekend Chicago took two of three from the Cubs and have now won seven of their last ten games to remain just a single game behind first place Cleveland in the American League Central. The Mariners lost three in a row over the weekend to San Diego and have now lost six of their last ten to fall into third in the AL West behind the Athletics and the Rangers.
The pitching matchup features left‑hander Noah Schultz for Chicago against right‑hander Bryan Woo for Seattle. Woo has been sharp recently putting together back-to-back quality starts, posting a 3.91 ERA with 47 strikeouts and a 1.00 WHIP overall on the campaign. Schultz, meanwhile, carries a 4.91 ERA and has struggled in his last two outings, allowing a combined 10 earned runs over eight innings. His command will be a key storyline tonight.
Offensively, the White Sox have leaned on Munetaka Murakami, who leads the team with 17 home runs and 32 RBIs. Andrew Benintendi has been hot, going 5-6 over the weekend against the Cubs. Seattle counters with Randy Arozarena, who leads the Mariners with a .301 batting average and Luke Raley who is the top bomber for Seattle with 10 home runs. The Mariners have relied heavily on power—owning a 10–4 record when hitting at least two home runs—while the White Sox have thrived when reaching eight or more hits, going 17–7 in such games.
This series pits two teams who could well be vying for the same Wild Card spot come October which makes this game and series in May all the more important.
