Seattle Mariners: Full Scouting Report on Each September Call-Up

The Seattle Mariners have yet to fully expand their roster to 40 players, but are slowly making some moves, adding eight players to the September roster.

While three of them haven't played yet in the majors, the other four have had some MLB work. 

Roster additions Tom Wilhelmsen, Mike Zunino, Carlos Triunfel and Hector Noesi have all played for the Mariners this season.

Taijuan Walker and Abraham Almonte made their major league debuts recently while James Paxton, who just arrived in Seattle, is eager to start his big league career. Chance Ruffin, who played for the Mariners in 2011, was recalled earlier this week.

Here are the scouting reports for the four players who have yet to appear in a game for the Mariners this season.

Abraham Almonte

2013 minor league stats: .300/.394/.482, 15 HR, 68 RBI, 26 SB (Double-A/Triple-A)

2013 major league stats: .235/.235/.294, 2 RBI (5 games)

Outfielder Abraham Almonte came to the Mariners in the Shawn Kelley deal with the Yankees. He's smaller in height at 5'9'', but makes up for it with his stocky frame at 205 pounds and can run, giving Seattle more speed in their lineup and a dependable outfielder who can cover some ground.

The 24-year-old Almonte displayed all five tools this season in the minors and made vast improvements offensively, proving he was finally ready to make the jump to the major league level.

Outfield has been a weak spot for the Mariners all season long, especially given their injury troubles. Almonte is a young and promising player who would fit nicely in Seattle's long-term plans.

Chance Ruffin

2013 minor league stats: 5-6, 3.91 ERA, 82 K, 29 BB, 112.2 IP (Double-A/Triple-A)

Pitcher Chance Ruffin appeared in 15 games for the Mariners in 2011 and pitched well, going 1-0 with an ERA a touch over 4.00 in 17.2 innings of relief. He had a decent strikeout-to-walk ratio of 2:1, but gave up a lot of hits and started 2012 in the minor leagues.

After taking a step backwards in 2012, Ruffin found himself in a new role this season for Double-A Jackson, starting games for the first time in his professional career. He went 4-4 with a 3.90 ERA through 16 starts and was promoted to Triple-A Tacoma where he started two games, but mostly worked out of the bullpen. 

Ruffin will likely be a reliever for the Mariners for the final month of the season, which could be a make-it-or-break-it proposition for Ruffin, who was a first-round pick of the Detroit Tigers in 2010 and is about to turn 25.

Taijuan Walker

2013 minor league stats: 9-10, 2.93 ERA, 160 K, 27 BB, 141.1 IP (Double-A/Triple-A)

2013 major league stats: 1-0, 3.60 ERA, 4 K, 3 BB, 10 IP

The long-awaited arrival of top Mariners' prospect Taijuan Walker has finally happened.

After impressing at every level of the minors, Walker made his major league debut against the Houston Astros and picked up his first big league victory, lasting five innings while surrendering an unearned run on a pair of hits. His second career start against Kansas City wasn't as smooth, but the Mariners won. Walker has a 0.90 WHIP through two starts (10 innings).

Walker is a huge part of Seattle's plans going forward and will be part of what the Mariners hope will be a dominant pitching staff.

James Paxton

2013 minor league stats: 8-11, 4.45 ERA, 131 K, 58 BB, 145.2 IP (Triple-A)

Lefty hurler James Paxton is another guy who's been mentioned in the trio of potentially great arms Seattle has in the minors along with Taijuan Walker and Danny Hultzen.

Although his numbers ended up being slightly less impressive at each level of the minors, Paxton has been given his shot to perform in the majors.

The Mariners will use a six-man rotation for the remainder of the season, meaning Paxton is scheduled to start Saturday against the Tampa Bay Rays at Safeco Field, according to The Seattle Times. It will be interesting to see how Paxton pans out, especially given the aforementioned decline in numbers we've seen from him recently.

With Paxton slated as the sixth starter, that means the Mariners' debut of Danny Hultzen will have to wait until next season at the earliest, unless he's called up and used as a reliever.
