Paxton slated to throw bullpen session Friday

SEATTLE -- Injured left-hander James Paxton played catch at Safeco Field on Monday and will do so again Wednesday before a scheduled bullpen session Friday as he works his way back from a shoulder issue that has sidelined him since early April.

Paxton has been on the disabled list since his second start of the year on April 8 when he strained the lat muscle behind his left shoulder. He worked his way back to the point where he made a Minor League rehab start for Triple-A Tacoma on May 24 before needing to be shut down again when his shoulder tightened up after that three-inning outing.

After another month of rehab, Paxton's starting to build his arm strength back up and the bullpen session will be another step along that way.

"I'm feeling really good," the 25-year-old said Monday. "I've been working real hard here trying to get myself ready again. Today was probably the best day I've had just in letting it go. I'm just working on getting my timing down and today was probably the best that's felt. One day at a time."

Manager Lloyd McClendon isn't putting a timetable on Paxton's return.

"He's doing extremely well," McClendon said. "How far away he is, I can't answer that. We'll just have to wait and see."

After working four straight days, Rodney gets night off

SEATTLE -- After pitching four straight games and recording saves in each of the Mariners' three wins over the Royals in a weekend sweep in Kansas City, closer Fernando Rodney was given Monday off by skipper Lloyd McClendon.

However, the hard-throwing 37-year-old insisted he didn't need or want the break as he's been on an outstanding roll over the past three weeks while allowing just one run in his last 15 appearances.

"I don't want a day off," Rodney said prior to Monday's series opener with the Red Sox. "I understand, but I'm ready to go. Whatever they say is their decision to make. I can do more than that, but I have to follow orders. I feel good. I'm ready to go, ready to compete."

When McClendon told Rodney he'd give him a break if he pitched his fourth straight on Sunday, Rodney jokingly told him he might fly home to the Dominican Republic with his day off. The two spent four years together when McClendon was a coach with the Tigers, and that relationship has been critical in Rodney's opinion.

"The important thing is good communication," Rodney said. "We were in Detroit together and he knows what kind of person I am and the kind of attitude I bring to the ballpark and how I talk to my teammates. I try to be happy and make jokes when they need it. And he understands."

The veteran closer went into Monday's games tied with the Royals' Greg Holland for the American League lead with 21 saves. Rodney became just the fourth Mariners closer in club history to hit 20 saves in his first 75 games of the season and the three previous relievers to achieve that all earned All-Star bids -- Kazahiro Sasaski in 2001, J.J. Putz in '07 and Brandon League in '11.

"That's a good number, 21 saves in early June," Rodney said. "Maybe it's surprising because sometimes we don't win, but I take advantage of every chance I get when we have save situations. I think that's good. We'll keep it quiet and not look back right now. I want to continue like that. If we just hit a little bit with runners in scoring position, I think we can get better because we've got a good bullpen."

Rodney, who was an AL All-Star for the Rays in 2012 when he racked up a career-high 48 saves, spent much of the early season pitching his way in and out of trouble. But he's been extremely efficient of late and has a 0.64 ERA over in 14 innings over his last 15 outings, with eight hits, two walks and 13 strikeouts.

In his last four games, Rodney pitched four scoreless innings with three hits, one walk and five strikeouts while facing just 15 batters. It was just the third time Rodney has worked four straight games in his career. He's never pitched in five straight games.

Rodney's 106 saves since the start of the 2012 season are second in the Majors behind only the 113 of Atlanta's Craig Kimbrel.

Worth noting

• Catcher Mike Zunino is second in the AL in times being hit by a pitch with nine in his first 60 games. That's the most times a Mariners player has been plunked in a season since Brendan Ryan's 10 in 2011.

• Right fielder Michael Saunders went 1-for-5 with a triple and an RBI in Sunday's rehab start with Tacoma, while designated hitter Corey Hart was 2-for-4 and first baseman Justin Smoak went 1-for-3 with an RBI.

Saunders has hit .417 (5-for-12) with a home run and four RBIs in three rehab starts as he works back from a sore right shoulder. Smoak is batting .222 (4-for-18) with one RBI in five rehab starts while recovering from a strained quad, while Hart is batting .375 (3-for-8) in two games back after dealing with a strained hamstring.
