Starting Pitching Matchup

White Sox

Sean Burke (11-7, 3.34 ERA, 1.20 WHIP) goes for the White Sox, and they have won his last three starts, in which he allowed only one run each. Chicago has won seven of his last eight starts, and he has given up more than two runs in one of his last five outings. In one start against Houston this season, he gave up two runs on four hits in six innings in a 4-1 loss. This season, Burke has worked 172 1/3 innings, striking out 185 and walking 62.

Astros

Hunter Brown (6-4, 3.19 ERA, 1.27 WHIP) gets the nod for the Astros, and they have lost his last two starts even though he gave up only two runs in 10 1/3 innings. In five starts this month, he has allowed no more than two runs in any of them and has an ERA of 2.73. He opposed Burke in Chicago at the end of August and had one of his best outings of the season, tossing seven scoreless innings and only allowing two hits in the Houston win. This season, Brown has logged 107 1/3 innings with 124 strikeouts and 55 walks.

White Sox vs. Astros Prediction: Under 7.5 runs

This one is a tough call because of the pitching matchup; both starters have been solid lately. Because of that matchup, I am taking the Under, even though the public is betting the Over at 62%.

Both Burke and Brown will pitch well in this game, and it will be unlike the last one, where Houston used eight pitchers and Chicago used five. Runs will be at a premium in this game, as Burke has allowed only one run in each of his last two starts and Brown has allowed no more than two runs in his last five starts.

Game 2 of this AL Wild Card series will be a lower-scoring affair, so back the Under tonight.
