Boston is 5-1 against New York, and Yankees owner George Steinbrenner is angry about his team's slow start, possibly disappointed enough that manager Joe Torre's job may be in jeopardy.
With both teams off today, the Yankees (9-14) ended the month 6Â½ games back of the AL East-leading Red Sox (16-8).
Tavarez (1-2) and four relievers held New York to seven hits, with Jonathan Papelbon pitching the ninth for his eighth save in eight chances.
New York's only runs came on a three-run homer in the third by Doug Mientkiewicz, who is hitting .154, and a solo shot in the eighth by Derek Jeter that extended his hitting streak to 17 games.
Chien-Ming Wang (0-2) couldn't hold a 3-2 lead, allowing four runs and six hits in six innings.
Ramirez became only the fifth player to hit 50 homers against the Yankees, joining Jimmie Foxx (70), Ted Williams (62), Hank Greenberg (53) and Carl Yastrzemski (52).
DETROIT - Brandon Inge's leadoff homer in the ninth inning lifted Detroit over Minnesota. Inge entered the game hitting .122, but had three hits, including the winning drive into the left-field stands off Jesse Crain (1-2) in the ninth.
Todd Jones (1-1), the third Tigers pitcher, got the win with a perfect ninth inning.
Johan Santana gave up three runs and eight hits in six innings for Minnesota. The AL Cy Young Award winner allowed two homers for the first time this season.
CLEVELAND - Fausto Carmona pitched into the ninth inning and Casey Blake homered to help Cleveland beat Baltimore.
Carmona (2-1) gave up six hits, walked two and struck out one in a career-best 8 1-3 innings. He had a shutout in the ninth before Aubrey Huff hit his 100th pitch over the wall in right with one out. Jay Gibbons then singled and Carmona was replaced by Rafael Betancourt, who got the last two outs.
It was Carmona's second straight win after a personal 11-game losing streak.
Cleveland struck quickly against Jaret Wright (0-3), who was activated from the disabled list before the game. Wright had been sidelined since experiencing shoulder soreness April 10 against Detroit.
It was his first career appearance against the Indians, who drafted him in the first round in 1994. The right-hander allowed three earned runs on four hits in 3 innings.
CHICAGO - Maicer Izturis and Vladimir Guerrero hit back-to- back homers, and Kelvim Escobar allowed four hits over 7 2-3 innings to lead Los Angeles over Chicago.
Former Angel Darin Erstad hit a two-run homer in the third, but Escobar (2-1) held the White Sox in check after that, striking out three and walking one. He left after walking Ryan Sweeney with two out in the eighth. Francisco Rodriguez came in and struck out Erstad, then pitched the ninth for his eighth save in nine chances.
Mark Buehrle (2-1) allowed nine hits over six-plus innings, walked one batter intentionally and tied a season high with eight strikeouts.
TORONTO - Alex Rios homered and Tomo Ohka pitched seven innings to win his second straight start for Toronto.
Aaron Hill went 3-for-4 and drove in two runs for Toronto. He has 17 RBIs this season, tying him with Vernon Wells for the team lead.
Ian Kinsler hit a two-run drive in the ninth for his ninth of the season, tying the Rangers' team record for home runs in April.
Ohka (2-2) gave up three singles in the first two innings, but didn't allow another hit until Jerry Hairston's one-out double in the seventh. Ohka gave up one run and five hits, walked three and struck out two.
Brandon McCarthy (1-4) lasted just three innings for Texas.
SEATTLE - Cha Seung Baek took a no-hit bid into the sixth, and Willie Bloomquist's two-out, two-run double in the seventh inning broke a 1-1 tie in Seattle's win over Kansas City.
Baek overpowered the Royals for six innings, and needed to as Seattle managed just four hits off Kansas City starter Brian Bannister (0-1).
Brandon Morrow (2-0) got the final two outs of the seventh and pitched a perfect eighth.
OAKLAND, Calif. - Rocco Baldelli, back after missing two games with a bruised right knee, combined with Elijah Dukes for back-to-back home runs in Tampa Bay's victory over Oakland.
B.J. Upton hit a go-ahead three- run homer in the fourth, connecting for the second straight game, then Baldelli and Dukes homered the next inning, the first time this season the Devil Rays hit back-to- back homers.
Scott Kazmir (2-1) shut down the A's as Tampa Bay won just its second series ever in Oakland.
Mark Ellis and Eric Chavez connected back-to-back in the first for Oakland.
Dallas Braden (1-1) took the loss.
