Texas Rangers closer Shawn Tolleson, armed with the leverage that comes with being eligible for salary arbitration, received a massive raise on a one-year contract on Monday.

The Rangers and Tolleson settled on a base salary of $3.275 million for this season. That is few dollars more than the midpoint between his request ($3.9 million) and the club's offer ($2.6 million) in arbitration.

It also represents a 531 percent raise for Tolleson, who earned $519,700 last season. He took over as the closer in mid-May and had 35 saves in 37 chances to tie for the fourth-best conversion rate in the majors.

The Rangers have two remaining arbitration-eligible players: left-hander Jake Diekman and first baseman Mitch Moreland. Diekman asked for $1.55 million, and the club offered $975,000. Moreland requested $6 million, and the club offered $4.675 million.

Manager Jon Daniels said on Saturday that the club continues to work on reaching settlements but is also preparing to go a hearing, if necessary. The Rangers last went to an arbitration hearing in 2000.

The Rangers have 18 players under contract at a total salary of about $135.3 million.
