Last week's ranking in parentheses
1. Rangers (4): They're 6-1 in starts by No. 5 and 6 starters Nick Tepesch and Justin Grimm. Move to the first spot because other teams ranked in the top 5 were 9-17 last week.
3. Braves (1): Happy to be getting home after 3-7 trip to Pittsburgh, Denver and Detroit. Back to business against the Nationals.
4. Red Sox (10): It's time to start believing in these guys, who had a majors' best +40 run differential through Sunday. John Lackey's strong start Sunday hints that the rotation could be five deep, with Ryan Dempster and Felix Doubront continuing their strong work.
6. Reds (5): Rookie Tony Cingrani worked 18 innings with a 1.50 ERA in his first three starts, including a win at Washington on Sunday. So much for the drop-off while Johnny Cueto recovers from a strained lat muscle.
7. Giants (2): Shortstop Brandon Crawford is continuing to emerge as one of baseball's true two-way players at his position. He's leading his team in homers with five.
8. Nationals (3): Rotation ranks fifth in NL in ERA. That's not bad but not as good as expected.
9. Orioles (11): Could Chris Davis wind up leading the league in home runs and RBIs this year? Probably not (his career OPS is .799) but he's positioned himself nicely for 35-plus homers and 100-plus RBIs, which would be a big step toward getting his team back in the playoffs.
10. Diamondbacks (12): Are they this year's Orioles? They're 6-0 in extra-inning games.
11. Yankees (14): Brian Cashman's late-spring roster restocking looked silly at the time. Not anymore, with the aging imports completely offsetting the run of injuries. Replacing right-hander Ivan Nova and catcher Francisco Cervelli is the latest challenge.
12. Athletics (7): They missed Yoenis Cespedes, who returned with a game-changing home run on Sunday.
13. Royals (13): Still not scoring runs like they did in the spring but averaged 5.6 runs last week, a big step forward.
17. Dodgers (16): Not a good sign that they've already needed nine starting pitchers, with Mike Magill the latest.
