ARLINGTON -- With September looming and his team fighting to stay in contention, Mariners manager Scott Servais said the club will likely add a handful of players to the roster on Friday, when rosters can be expanded for the final month.
"We need some more healthy bodies," Servais said. "You're probably looking initially at four or five guys. Then we'll kind of see where the [Triple-A] Tacoma season plays out. They're fighting for a playoff spot, so we'll see where we go after that."
All seven of the Mariners' Minor League affiliates have qualified or are fighting for postseason berths. The Minor League seasons end Monday, but the club will let some of its young prospects finish out the playoffs before adding them as well.
"It's good news," Servais said. "I'm really happy with the job our Minor League system has done. The year they've had is phenomenal. It's been a great turnaround there. They all should enjoy that. But you'll probably only see four or five guys at the beginning [because of the postseason plans]."
With an off-day on Thursday, the Mariners will wait until Friday to add anyone, and they're expected to bring up reliever Evan Scribner and catcher Jesús Sucre, as well as possibly a corner outfielder to help out defensively and another pitcher or two. David Rollins and Cody Martin, two pitchers who've been with Seattle several times already this year, are possibilities. Daniel Robertson is an outfielder who could fit the bill as well.

Sucre will provide a third catcher behind Mike Zunino and Chris Iannetta. Sucre's hit .255 in 27 games for Tacoma since returning from a fractured leg and also went 1-for-8 in three games for Seattle in two brief stints with the club.
Scribner threw a scoreless inning with a walk and a strikeout in Tacoma's 5-3 victory over Fresno on Tuesday in his fourth rehab outing with the Triple-A club as he returns from a season-long issue with a torn lat muscle behind his right shoulder.
The right-hander will provide another option for Seattle's bullpen, and more relievers figure to be added soon, as Drew Storen is eligible to come off the 15-day disabled list on Sunday and Tom Wilhelmsen on Sept. 9.
Tony Zych is another possible addition, as he's eligible to return on Monday, 10 days after he was optioned. But Zych's shoulder was sore after his last outing, and he was placed on the seven-day Minor League DL on Tuesday.

Outfielders Norichika Aoki and Stefen Romero and infielder Mike Freeman are among the other likely additions as soon as they are eligible to return later next week or once Tacoma's season ends.
Worth noting
• James Paxton had a nail hardener applied to his troublesome middle finger on his left hand on Wednesday morning, and he hopes that will help solve an issue that popped up again in Tuesday's start against the Rangers.
Paxton threw five innings in the game, but he was dealing with the finger from the third inning on. The same issue caused him to miss some time at the end of last season. The 27-year-old will throw a bullpen session on Friday at Safeco Field to test the nail prior to his next scheduled start Monday against the Rangers.
"That will determine where we're headed there," Servais said. "I'm expecting him to make his start, and he's expecting to make it. The big thing is, I hope he can use all his pitches. Last night, it kind of limited what he could do pitch-wise. On the cutter and changeup, it was bothering him more than the fastball. But he didn't have the velo we're used to seeing either, and that probably had something to do with it."

• The Mariners' Double-A club in Jackson made history Wednesday as the team claimed each of the three major postseason awards in the Southern League. Tyler O'Neill was named the league's Most Valuable Player, Ryan Yarbrough was named Most Outstanding Pitcher and Daren Brown earned Manager of the Year honors. It is the first time since 1991, and only the third time in Southern League history, one team has had the winner of all three awards.
