Bits: Arencibia's power, Nats bullpen ...

New York Yankees lefty Andy Pettitte tossed six shutout innings at Minnesota on Monday, the second consecutive start in which he didn't allow a run. Pettitte allowed seven hits and a walk, and lowered his ERA over 11 starts to 2.71. He's a terrific free-agent addition for Saturday at Toronto, and if there's a one-game playoff at the end of the regular season, Pettitte, available in more than half of ESPN standard leagues, stands in line to start it.

Josh Hamilton owners had to be pleased to see him in Monday's lineup for the Texas Rangers after missing five games due to an eye problem. Hamilton homered and scored twice, and should be back in all lineups, especially with the Rangers at home all week. Hamilton has played 139 games so far, which might be more surprising than his spectacular power numbers.

Toronto Blue Jays catcher J.P. Arencibia smacked a grand slam and knocked in five runs Monday, his first home run since July. Arencibia missed five weeks because of a broken hand and was really struggling this month, with two hits in 36 at-bats. He certainly brings potential for big power numbers, but at a terrible price in terms of batting average.

• Speaking of a low batting average, New York Mets first baseman Ike Davis is hitting .227, but his pair of home runs and five RBIs Monday sent his season totals to 30 home runs and 88 RBIs. That's very good, and since Davis has done his best work on the road (.890 road OPS, 20 home runs) and rumors persist that he could be traded, there's plenty of upside for 2013.

Milwaukee Brewers right-hander Marco Estrada entered Monday as one of fantasy's most-added pitchers, with a 1.22 ERA in his past six starts. Then the NL East champion Washington Nationals tagged him for seven runs (six earned) in four innings. Estrada is 29, far past prospect status, but he's a nice strikeout option and someone to watch in 2013.

• Speaking of the Nationals, the team with the best record in baseball is changing closers two weeks before the playoffs. Both Tyler Clippard and Drew Storen pitched Monday, but before the game, manager Davey Johnson said Storen would take over closing duties. Storen, owned in roughly half of ESPN's leagues, has allowed runs in only three of his 32 appearances. Feel free to drop Clippard, despite his 32 saves (and 9.72 September ERA).
