Q: Green shored up the 1984 roster with a series of transactions. In December, 1983 Scott Sanderson was acquired from Montreal in a three-team deal with San Diego for Carmelo Martínez. Pinch hitter Richie Hebner (.333 BA in 1984) was signed as a free-agent. In spring training, moves continued: LF Gary Matthews and CF Bobby Dernier came from Philadelphia on March 26, for Bill Campbell and a minor leaguer.
