Ishikawa (back) has suffered a setback and is not expected to play any time soon, John Shea of the San Francisco Chronicle reports. Ishikawa had been scheduled to embark upon a rehab assignment for Triple-A Sacramento, but the Giants will hit the pause button on this plan, instead electing to keep him with the team for treatment. He's already eligible to return from the disabled list, but considering the lack of a concrete timetable, he may be out of action for quite a while longer. Ishikawa would have represented one of the final 25-man roster spots anyway, so is unlikely to hold much fantasy value down the stretch, even when healthy.

Ishikawa (back) will begin a rehab assignment with Triple-A Sacramento on Saturday, CSN Bay Area reports. Ishikawa is eligible to come off of the disabled list Sunday, and the club will likely give him a game or two of work in the minors before activating him. When Ishikawa returns, he will serve as the primary backup at both first base and left field.

Ishikawa (back) was placed on the 15-day DL on Saturday, John Shea of the San Francisco Chronicle reports. An MRI earlier in the week revealed no serious damage to Ishikawa's back, but the injury will delay him long enough to where a DL stint will be necessary. Ishikawa did not enjoy much success this spring, going just 9-for-47 (.191 average) with two extra-base hits (one homer), but he will return to a bench role once healthy, perhaps replacing Justin Maxwell or Brett Jackson on the active roster.

Ishikawa (back) looks poised to start the season on the DL, the San Francisco Chronicle's Henry Schulman reports. He will stay in Arizona to get minor-league at-bats, therefore allowing the Giants to back-date a DL stint. This would allow Matt Duffy to break camp with the team in a bench role until Ishikawa is healthy enough to rejoin the team.

Ishikawa (back) had an MRI that revealed no serious damage resulting from Sunday's injury and will return to action Thursday, Andrew Baggarly of the San Jose Mercury News reports. Ishikawa left Sunday's game with a back injury, but it turned out to be a minor ailment. Assuming he doesn't suffer a setback Thursday, he should be on the Opening Day roster.

Ishikawa left Sunday's Cactus League game with a back injury, and he will be reevaluated Monday, Andrew Baggarly of the San Jose Mercury News reports. The injury doesn't sound overly serious, but with Opening Day only a week away, Ishikawa doesn't have much time to recover. If healthy, he'll likely make the Opening Day roster, as Hunter Pence (forearm) is expected to miss at least the first few weeks of the season.

With Hunter Pence (forearm) likely to start the year on the DL, Travis Ishikawa is the likely candidate to claim his spot on the 25-man roster. Ishikawa played such a vital role in postseason of the Giants' 2014 championship run that they re-signed the journeyman to a one-year deal this offseason. With Pence going down this spring, manager Bruce Bochy will likely carry five outfielders to shuffle in and out of the lineup for the start of the season, and Ishikawa is a strong candidate to be one of the five. He is slashing .269/.406/.462 through 26 at-bats this spring.

Ishikawa signed a one-year, $1.1 million deal with the Giants on Thursday to avoid arbitration, MLB.com's Chris Haft reports. Ishikawa slashed .252/.311/.393 with the Pirates and Giants during the 2014 regular season, but played meaningful innings for the Giants during their World Championship run. Rather than go to arbitration, the Giants inked him to a short-term deal, locking the 31-year-old up as an outfielder and backup first baseman for the 2015 season.

Ishikawa is out in the lineup for Game 4 of the World Series on Saturday. With southpaw Jason Vargas on the hill for Kansas City, manager Bruce Bochy will turn to the right-handed-swinging Juan Perez to man left field. Ishikawa is 1-for-7 with two strikeouts so far in the series, but he should be back in there Sunday to face off against James Shields.

Ishikawa hit a walk-off three-run home run Thursday to win Game 5 of the NLCS and send the Giants to the World Series. It is the first home run to end an NLCS and fourth to end an LCS. Ishikawa started the year with the Pirates before being designated for assignment in mid-April. The Giants signed him to a minor-league deal but did not call him up from Triple-A until late July. Ishikawa jumped on a 2-0 fastball from St. Louis' Michael Wacha and sent it into the right-field seats.
