Casey Kelly debuts, Thames homers again

San Diego Padres right-hander Casey Kelly won his major league debut Monday, tossing six innings of three-hit shutout ball. Kelly, a prize from the Adrian Gonzalez trade to the Boston Red Sox, missed much of this season because of elbow inflammation, but at three levels of the minors, his ERA was 3.35, with three walks and 39 strikeouts. Because he pitches in Petco Park, Kelly is a viable spot starter the rest of the season.

• Speaking of former Red Sox property, right-hander Josh Beckett lost his Los Angeles Dodgers debut Monday at Coors Field 10-0. Beckett was charged with three of the runs in 5 2/3 innings, permitting seven hits and three walks. Sure, it's Coors Field, so expectations were low, though the Rockies spun a shutout. Beckett's numbers should improve some in the NL, but he's no ace. Use him at home against the Diamondbacks this weekend.

• Meanwhile, current Red Sox right-hander Daisuke Matsuzaka won his first game of the season Monday, allowing an unearned run in seven innings and striking out six. Matsuzaka has made only six starts this season, and this was only his second quality start. Now 31 and four years removed from fantasy relevance, Matsuzaka dazzled the Royals with his slider and cutter, but he isn't a 10-team add just yet. Let's see where Dice-K is pitching next season, and if he's healthy, before buying in.

Toronto Blue Jays outfielder Colby Rasmus launched a three-run homer off New York Yankees closer Rafael Soriano on Monday. For Rasmus, who continues to struggle with his batting average, it was his 21st home run, two off his career best. He hit .276 that year (2010) and stole 12 bases. This version of Rasmus (.234), even with the power, isn't emerging as a star. As for those concerned about Soriano, those were his first runs allowed in August. He's not losing the role to David Robertson anytime soon.

Seattle Mariners outfielder Eric Thames provided King Felix Hernandez the only run he'd need Monday, launching an eighth-inning home run in the 1-0 win. Thames has hit four home runs in 23 games for Seattle, after managing three in 46 games for the Blue Jays earlier this season. Although Thames hasn't emerged as a reliable fantasy option, there's upside for 20 home runs in a full season, and he does have three blasts in the past week.
