Jason Giambi career home runs, season by season

Season↓	Team↓	GP↓iGP: Games the player appeared in, however briefly.	AB↓iAB: At-bats: trips to the plate that ended in a hit, an out or an error. Walks and sacrifices are not counted.	R↓iR: Runs — scored by the batter, or allowed by the pitcher.	H↓iH: Times the batter reached base by hitting the ball, without help from an error.	HR↓iHR: Home runs hit.	RBI↓iRBI: Runs that scored because of this batter's plate appearance.	SB↓iSB: Bases taken while the pitcher was delivering. Being caught is counted separately.	AVG↓iAVG: Hits per at-bat. .300 is the traditional line between a good hitter and a great one.	OBP↓iOBP: Share of plate appearances that ended with the batter on base — hits, walks and hit-by-pitches.	SLG↓iSLG: Total bases per at-bat, so a home run counts four times a single.	OPS↓iOPS: On-base percentage plus slugging. Around .800 is All-Star level, .900 is MVP territory.
