Notable nuggets on the upcoming weekend action that could swing your fantasy baseball matchup:
• The White Sox promoted Andre Rienzo to the majors after sending Jake Peavy to Boston in a three-team deal that also involved Detroit. In his first two starts, Rienzo has surrendered just two earned runs in 13 innings, striking out nine while allowing 15 base runners. He had a great year at Triple-A Charlotte, going 8-6 with a 4.06 ERA, 3.33 FIP and exactly one strikeout per inning, whiffing 113 batters in 113 frames. He'll make his third start of the year Saturday against the Twins, who have been a largely cooperative offense this season.
• Alex Wood found his way into this column last week, and he ended up earning his spot by tossing six innings of one-run, two-hit ball against the Phillies. He remains widely available, and is a great stream option again this weekend, as he'll take the ball for the Braves against the Marlins on Saturday. The Marlins have played a whole lot better lately, but they still don't feature a lineup anyone would describe as potent. If you can only stream one pitcher on Saturday I prefer Rienzo, but not by much.
• The Rangers' Martin Perez has been hot of late, dominating the Angels in back-to-back starts. In 13.2 innings, he gave up just three runs on eight hits, striking out 11 batters. He did walk six, but the outings stand as two of his strongest of the year. He'll get a great chance to build on them this weekend, drawing the hapless Astros on Sunday. You're not going to find a better option than Perez on the final day of the week. Get him in there if you're chasing.
