Angel Pagan

The Mets were busy Tuesday, agreeing to send center fielder Angel Pagan to the Giants for outfielder Andres Torres and pitcher Ramon Ramirez, and coming to an agreement with free agent relievers Frank Francisco and Jon Rauch.

Francisco’s deal is for two years and $12 million. Rauch has a one-year deal worth $3.5 million, with $500,000 in performance bonuses.

“We rebuilt our bullpen in one day,” Mets manager Terry Collins said, adding: “No disrespect to our guys, but we couldn’t stop some teams. I think we can now.”

Francisco, 32, pitched last season with the Blue Jays after six season with the Rangers. He had 17 saves in 21 chances in Toronto, compiling a 1-4 record and 3.55 ERA.

Rauch, 33, also played for the Jays in 2010, going 5-4 with a 4.85 ERA and recording 11 saves in 16 chances.

The 33-year-old Ramirez, who pitched for the Red Sox in 2009, was 3-3 with a 2.62 ERA for the Giants this past season.

Torres, 33, hit .221 with four home runs and 19RBIs in an injury-plagued season (Achilles tendon strain).

Pagan, who took over center field from Carlos Beltran, hit .262 with seven home runs and 56 RBIs.
