Brooks and Brett, Northey and Christian, Spinks and Lampard—these are the names of youngsters being brought up from the minors for a late-season look. For the most part, it is The Charge of the Very Light Brigade, a group of fuzz-cheeks who fade away after taking a few futile swings or watching their pitches disappear into oblivion. Some, though, lose the near-anonymity of mere boxscore listings and make the wire services' stories with their full names. Nowhere was this mass influx of newcomers more evident than among the Yankees, who used five in one game—Frank Tepedino, Dave McDonald, Ron Blomberg, Thurman Munson and John Ellis. Munson, 22, and Ellis, 21, both set up wins last week with late-inning hits. The new recruits include a spate of outfielders such as Bob Brooks, 23, of the A's, Bob Christian, 23, of the White Sox and Scott Northey of the Royals, the 22-year-old son of former big-leaguer Ron Northey. Brooks beat the Royals 3-2 with a homer and 10th-inning single, and Christian had three homers. Northey, who has the speed his father lacked, had two triples and a stolen base in one game and last week hit .444. Impressive pitchers include Ken Brett, 21, of the Red Sox, who won twice in eight days, and Scipio Spinks, 22, of the Astros. Spinks fanned four in two innings and also established himself as a blithe spirit by stealing the feathery headdress from the Brave mascot. Chief Noc-A-Homa. No one, though, made more of an impact than Keith Lampard, 23, of the Astros, who had three hits in four pinch-hitting roles, one a two-run homer in the ninth to beat the Reds 3-2. Now, if he kept that pace up.... Of such wishful things are dreams of next year made.
