[12/12/2017] Tomoya Mori returns to Japan after hurting knee

The Seibu Lions announced on December 12 that Tomoya Mori will return to Japan after he hurt his left knee. Mori felt discomfort in the knee while running out an infield grounder during a Melbourne Aces game three to four days ago.

Mori’s condition does not seem to be serious, but the Lions did not want to take any chances and decided to call him back from Australia. He will undergo tests after he returns to Japan.

Tomoya Mori: Did You Know



Mori was invited to be a part of the Samurai Japan top team for the Asia Pro Yakyu Championship, but Seibu turned down the invite because they want him to focus on improving his skills as a catcher. Mori is set to play winter ball in Australia.

Mori moved out of the Seibu Lions dormitory and started living on his own about a year ago. He relied on gyudon for weight gain and overdid it a bit — his weight went up to eighty-six kilograms. Mori is planning to cut back the gyudon and focus on vegetables to lose about three kilograms during the winter. The weight loss should help take some of the strain off his knees.

Tomoya Mori left a game against WBC Cuba on March 5 early because he took a pitch off his left elbow during his at bat in the fourth inning. He left the field for treatment and did not return. He told reporters after the game that he was okay.

[UPDATE 3/29 @ 11:29pm]

Surgery was a possibility, but Mori and the Lions opted for non-surgical treatment. He is slated to begin a rehab program in April. He will most likely require more than two months for a full recovery.

Source: Daily Sports 3/29/2017

[UPDATE 5/6 @ 5:41pm]

Mori tossed batting practice at Seibu 2 Stadium earlier today. He spent about thirty minutes throwing over 150 pitches to Yuji Kaneko and Aito Takeda. Based on his current progress, he might not be ready to return to the active roster until some time after Inter-league play.

Source: Tokyo Sports 5/6/2017

[UPDATE 6/14 @ 2:39pm]

Mori is making slow progress. An examination revealed that the fracture in his left elbow was still not fully healed. There is also a difference in size of two to three centimeters between his arms. He might not be ready to play in rehab games until some time in late-August.

One big reason for the slow progress might have something to do with Mori’s decision to go with non-surgical treatment.

[UPDATE 7/29 @ 7:09pm]

Mori is taking batting practice against pitching machines and catching Ni-gun pitchers in the bullpen, but has not yet participated in team batting practice sessions. He might still need another half-a-month to a month before he is ready to take the next step. At this point, his focus is most likely the 2018 season.

[UPDATE 8/8 @ 10:30pm]

Mori entered a Ni-gun game against Nippon Ham as a pinch-hitter in the sixth inning and grounded out to third. It was his first game in about five months.

[UPDATE 8/9 @ 4:58pm]

Mori entered the game as a pinch-hitter in the third against Nippon Ham today. He hit a grounder to second and reached on an error in his first at bat in the third inning and hit a two-out solo home run to left in his second trip to the plate in the fifth inning. He took over at catcher in the fourth and worked two innings.

Added additional performance information on 8/9 @ 8:48pm.

[UPDATE 8/11 @ 11:48pm]

Mori hit a two-run homer against Ni-gun Rakuten earlier today.

[UPDATE 8/15 @ 8:22am]

There is a good chance the Lions will add Mori to the active roster today. He will most likely be used as either a designated hitter or pinch-hitter, since he has only played one full Ni-gun game at catcher.

Mori went 4-for-12 with two home runs in four Ni-gun rehab games.

[UPDATE 2/23 @ 12:12am]

Mori went 1-for-2 (1B9, BB, L3) in a Ni-gun practice game against Hanwha on February 21. He also played in a Ni-gun practice game against Hanshin on February 18. He participated in joint Ichi-gun/Ni-gun practices on February 22 and will play in a Ni-gun game against Hanshin at catcher on February 23. Assuming no issues, he will most likely join the Ichi-gun team on February 24.

[7/26/2016] Tomoya Mori to get first start at catcher since 2014

Tomoya Mori is slated to get a start at catcher on July 29 against the Orix Buffaloes at Kyocera Dome. It was be his first start at catcher since October 1, 2014.

The Lions are planning to use Mori as a catcher on July 29 because they want his bat in the line-up. Takeya Nakamura has spent a lot of time as a designated hitter since mid-May and Yuji Kaneko has started getting more starts in right (and third). The Lions can have a much deeper offense if Mori can catch.

[5/28/2016] Tomoya Mori could return to the active roster on June 3

Tomoya Mori could return to the active roster in time for the start of an Inter-league series against Hanshin at Koshien Stadium on June 3. He will most likely be used a bat off the bench.
