Tavarez determined to deny Sosa

Boston (33-15) at Texas (18-31), Sunday, 3:05 p.m. ET

Julian Tavarez and Sammy Sosa are fellow Dominicans and former Chicago Cubs teammates. But to hear Tavarez tell it, that's as far as the affinity goes.

"I don't have no friends, not in baseball," Tavarez said. "I can't call him my friend, because if they hit one of my guys and I have to go out there, I'm not going to be sorry for hitting Sammy. You can't call it 'friends' like that.

"When you're on the field, you don't have no friends. Because sometimes you've got to do things and you can't feel sorry for that."

But assuming that Sunday's finale of this three-game series in Texas doesn't involve retribution or protecting teammates, Tavarez knows his confrontations with Sosa still will carry a buzz. With 598 career home runs, Sosa is on the verge of becoming just the fifth player in history to hit 600.

"I only know Sammy is a home run guy," Tavarez said. "He's been one of the greatest players in baseball. He was a good teammate when I was with the Cubs (2001), and I'm glad that he's doing good and has come back and is going to reach his goal."

After a rough 2005 season in Baltimore (.221, 14 HR, 45 RBIs), Sosa did not play in 2006. But at age 38, he was offered a comeback opportunity with the Rangers, the organization that originally signed him as a 16-year-old free agent in 1985. He has repaid the debt by leading the Rangers in home runs (10) and RBIs (37) despite playing only 43 of the team's first 49 games.

But if Sosa is to reach the 600-homer milestone before hometown fans, he'll have to hurry. After Sunday, the Rangers leave on a weeklong road trip to Oakland and Seattle. Tavarez understands the significance of Sosa's next few at-bats.

"It doesn't matter," Tavarez said. "I don't want to be the one [to surrender the milestone home run], but if it happens, it happens. But I'm not going out there thinking, 'I'm going to be the one.'"

Sosa has taken Tavarez deep just once in his career, and that was a solo shot just over a decade ago. He hit his 180th career homer off Tavarez on May 18, 1997, when the right-hander was a youngster pitching for the Giants. Overall, Sosa is 5-for-18 (.278) with two doubles, four walks, three strikeouts and one home run against Tavarez.

Tavarez said he won't avoid Sosa, even at the risk of becoming an historical footnote. He said the only way to approach the slugger is to pitch him aggressively.

"You have to just go after him," Tavarez said. "Even to Manny [Ramirez]. Manny's my best friend, but if I had to do it to Manny, I would do it, because that's the way it is in this game."
